i V Thisinventionrelates to incendiary bombs,

and" it is an obj ect' of the invention to provide a deviceof this kindwhichfis' small in size yet highlyelfective in use.

id provide a device of thiskind provided with tail Wingsifor guiding the bomb in its flight and which wings are of a highly inflammable character to assist in the] starting of the desired conflagrationl 15 I'Thej invention consistsin' the details of construction and in thecombinationand'ar rangement of the several parts of my im- 1 proved incendiary bomb whereby certain important advantages are attained and the de- '20 vice rendered simpler, lessfexpensive and i 1 otherwise more convenient and advantageous foruse,'-asi'willbe hereinafter more fully set for h a 'i ""jlhe novel features of my invention will 25 hereinafter be definitely claimed.

In order that 1 my invention may be the better understood, I will now proceed to describe the same with reference to the: accompanyingdrawing,wherein: 30 Figure l isf-a view in top plan of the rear 1 end of a bomb constructed in accordance with an embodiment ofmy'inve'ntion;

Figure 2-is aview in side elevation of the a bomb as hereindisclosed; j Figure Bis -an enlarged longitudinal fsec tional view taken through the device as herein 1 Y embodied with certain of the parts in elevation;

FigureV i a in elevationunapplied '4 of one o'f' the tailfinembers' herein employed.

My improvedbomb as herein disclosed comprises an elongated cylindrical body member 1 of wood orkindred materialfsaturated with kerosene or other inflammable material and 46 which saturated "material is held vagainst evaporation by a coating 2 of wax; or the like disposed over the peripheral surface of the y N body member 1. This body 1 has one end portion gradually reducedin diameter to pro- 5 Vide apoint-like extremity to" facilitate the llppl ication and February 11, 1932. Serial l \T0. 592 36;.

travel of the device through the air, and said body 1 axially thereof is provided with a bore 4 of a relatively large diameter. The bore 4 at the rear end of the body 1 is inter sected by a kerf 5 disposed radially of said P end portion of'the body 1.

The rear end of'the body 1 at opposite sides of thekerf 5, as particularly illustrated in Figure 1, is provided with diametrically aligned and relatively deep pockets 6 within 60 each of which is snugly engaged a filler 7 of highly inflammable material and each of which fillers 7 has extending outwardly therefrom a relatively long wick 8. f

The forward or pointed end portion 3 of the body 1 has fitted thereon a cap 9 preferably ofmetal and which provides a sheathing for the forward end of the body 1 to facilitate the passage of the bomb into or through its target. This capor shell 9 extends in advance of the blunt or flattened forward end 10 of the body land has its forward extremity provided with aninwardly disposed cup-like member 11 adapted to have placed therein a percussion cartridge 12 or kindred element.

Disposed through the bore 4 of the'body l is a slow burning fuse 14, the forward end of which terminates in close proximity to the applied cartridge 12. The opposite end portion of this fuse 14 carries a highly inflammable mass or body 15 which readily and quickly bursts into flame upon being reached by the fire or spark travelling upalong the fuse 14 and which fuse 14 is ignited by the flame produced by the firing of the cartridge 12 The outer end portion of the cap 9, as herein disclosed, is provided with a series of inwardly disposed fingers 16' or the like which hold substantially into contact with the applied cartridge 12 a spherical member 17 of metal and which member 17 as a result of impact results in the desireddischarge of the cartridge 12 whereby is obtained the desired ignition of the slow burning fuse 1 1.

Inserted within the kerf 5 in the body 1 is a plate 18 of a highly inflammable material and which plate is of a width substantially equal to the diameter ofthe bodyl and isheld in at desired position "with respect to the body -1 to a wall of the kerf 5 by'a suitable adhesive,

as indicated at 19 in Figure 2. The lower central portion of this plate 18 is cut-out, as at 20, so that the plate 18 when applied Wlll.

bridge the body or mass 15, thus allowing the plate to be applied as desiredand in a way to be readily subjected to the flame from the mass or member When burning. This plate 18 is of a size to extend-beyond the rearv end of the body 1 when applied and said extended portion is provided with the spaced openings 21 through each of which is adapted to be threaded or inserted a wick 8 so that said wick 8 will be ignited upon, burning of the plate 18 so that the requisite fire will be carried to theinflammable fillers 7 to further facilitate the igniting of thebody 1, l V I e I lso extending within the kelrf at the rear portion of the body 1 is a second plate 22also of a highly inflammable material, this plate being secured by a'suit'able adhesive,as at 23,

to the second wall of the kerf 5. This plate 22 also has its central portion cut-away, as at 24c, to bridge the wicks 8 threaded through Upon. the. bomb striking its target-as itv passes through or into the target under the force of impact the possible stripping of the plate 22 fronithe body 1 will in no way affect the appliedplate 18 which does not extend beyond the peripheral. surface of" the body '1. As the bomb strikesits targetasibefore ex plained, the cartridge 12 is exploded resulting in the ignition of the fuse 14; whereby through the flamefrom the mass or member 15 and the ignited plates 18 and 22 fire will be carried by theWicks8 to the inflammable fillers 7. Of course, the flame from the plates 18 and 22 asw'ellas from the mass or member 115 will also tend to ignite the body memberl.

' It is also of advantage todispose radially through the body member 1 at desired points therealong the'openings 25 each of which having'appli e d therein a filler 26 of pitch or the like and which filler as a result of the heat from the burning bomb will melt and spread over the target whereby the resultant ignition of such spread pitch or the like will further assure the incendiary value of the bomb.

The upper portion of the plate 22 at the central parts of its cut-out portion 24: is provided with an inwardly disposed projection 27thereby providing means for holding the fuse 14: togetherwith its inflammable mass or member 15 in applied position within the body 1..

""From the. foregoing description it is thoughtto be obvious that an incendiary bomb constructed in accordance with'my invention is particularly well adaptedfor use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious thatmy invention is susceptible of some change and modification Without departing from the principles and spirit thereof and for this for igniting the fusea 3.
